T 0 all whom 2'6 mm! concern:

Be it known that we, SAMUEL E. AUTREY and Josnrii ii, llli'rcHELL,citizens of the United States, residing at Sherman, in the county ofGrayson and State of Texas, have invented certain new and usefulImprovements in Gas Generators and Burners, of which the following is aspecification.

This invention relates to a combined gas generator and burner forkerosene oil, and it particularly relates to a device of this characteradaptedto be employed in connection with ordinary cooking and heatingstoves, furnaces, and the like, or for divers other purposes.

An object of the invention is to provide a device of this characterwhich may be fitted into the fire-box and seated upon the grate ot'stoves of diiierent sizes, and which shall be comparatively simple,durable, and inexpensive in its construction, as well as being practicaland efi'icient in op oration.

A further object of the invention is to provide a burner embodying aretort in con nection with a superheating pipe vvhereby the retort, inhein heated, will vaporize or gasify the liquid tuel in order that thegas or vapor may be heated to a high temperature in the superheaterpipe, and a most effective combustion of gas result to produce a maximumheating etiect with a minimum expenditure or" fuel.

This invention also embodies various subordinate features oiconstruction and combinations of parts, all subservient to the broadfeatures above outlined, which will be more fully described hereinafter,illustrated in the accompanying drawings, and finally pointed out in theclaim iereunto pended, it being understood toat changes in the preciseembodiment of the invention herein disclosed canbe node within the scopeof what is claimed without departing from the spirit of the invention.

The invention has been illustrated in its preferred i'orxn in theaccompanying draw iii-gs, wherein Figure l representsa front elevationof a stove with the burner applied, portions being broken away. Fig 2 isa plan view of enlarged detail view of one of the retorts removed.

Referring more particularly to the in which similar reference numeralsdesignate corresponding parts throughout Patented Mar, i l, 191%Application filed July 26, 1915. Serial No. 42,001.

the several views, 1 indicates a stove or" ordinary construction and 2the usual grate bars thereof. A suitable rectangular base 3 is seatedupon the grate bars and extends longitudinally nearly the length of thefirebox a. A pair of cylindrical retorts, 5 and 6, are seated upon thebase, one near each end tiereof, and centrally located and secured tothe bottom of the retorts are tubes 7 8 that extend upwardly Within themfor about two-thirds their height, and downwardly through their bottomends, also, through apertures in the base 3, Where 'elbows 9 and 10 areattached thereto; the downward projecting ends of the tubes being of theproper length to permit the connected ends of the elbows to restadjacent to the under side of the base 3, and thus serve to retain theretorts securely in nosition upon the base. To the other ends of theelbows 9 and 10 are connected oil supply pipes 11 and 12, that aredisposhd horizontally beneath the base, to and throughi an opening inthe door at the opposite end of the stove, whence they branch laterallyas shown at 13 and i l, and are fitted with the usual angle oil supplyvalves 15 and 16, which valves are in turn connected with the top sideof a laterally disposed oil receiver 1?, through vertical check valves18 and 19,

The retorts 5 andfiare filled with small as, tor instance, screws clown,

deflectors or spreader-s 28 and 29, centrally located ov r the gas getsand apt-ed to spread the flame when the (an said jets is burning. Smalllras w res 539 are *osed within the superheating pipes to 51st inheating the va'oo r a,

A fuel supply tuuk 35 may besup ported in any convenient manner above the level of the burners andconnected with the bottom side of the reservoir 17, by a pipe 36. inoperation, liquid fuel, such as coal oil, or the like may be fed bygravity or under pressure, from the supply tank, through the supplypipe, and. check valves, Where the quantity thereof is regulated by thevalves 15 and 16, and the oil continues its course thence and flowsthrough the pipes 11. anal 12, and initially, to the retorts 5 and *5,through the superheating and burner sections, and out through the jets36 end 27 and partly fills the priming pens 31. and.

W hen the pri nary chergmg supply of oil is consumed,oil will er only slowly ooze frezn the tubes .i 8, to the pebblescontained 111 torts which being very hot, vupoi'izes the by LettersPatent of the Unitecl States, is-- in a gas generator and burner forstoves and the lihcyu base, a retort at each end of the base andsupported thereby absorbent materiel and an upstanding tube in eachretort, said tubes connected. through the bottom ends of the retorts toliquid. fuel. supply pipes, e pipe connected with the to of each retortthat comprises superheeting and burner sections, the letter having e jete ening therein, and means for supplying liquid fuel to the i'uel supplypipes, as set ioi'th, In testimony whereof We ailix our SlgMt tures inpresence of two Witnesses.
